Plasma exists only at very high temperatures and isused by plasma cutting systems to cut electrically-conductive metalsvery neatly and very quickly. A CNC Plasma Cutter adds specializedsoftware that controls and directs the plasma cutting torch with speed,accuracy, efficiency and repeatability.Put simply, plasma is agas that has been compressed and energized to the point that some ofthe electrons break free from and travel with their nucleus. A nozzleat the cutter’s tip concentrates the gas and introduces a spark, andturns the gas stream into plasma. Inert or semi-inert gases are used toshield the area where the plasma touches the metal.
The force of theplasma is strong enough to blow the molten metal out of the work piece,creating a thin (less than a 1/16″ wide), clean cut with little or noslag. The plasma itself reaches temperatures as high as 30,000 degreesFahrenheit and easily cuts through 2″ inches of metal.The partof a CNC plasma cutter that makes it so LONES PLASTIC MACHINERY CO., LTD. incredible efficient is theComputer Numerically Controlled (CNC) software. The CNC software, withthe help of the computer, controls and directs the plasma cutting torchwith speed, accuracy and efficiency. Computer-based software programslike CAD/CAM are an integral part of each CNC machine tool.
The CNCsoftware also assures precise handling of the machine and exactingdistances between the plasma nozzle and metal sheet. CNC softwareususlly includes nesting capabilities, making the plasma cutter evenmore efficient.Plasma cutters come in all shapes and sizes. Whatmakes the difference between them, is their construction and theircomponents. High quality units feature solid, heavy-duty, fully welded,unitized construction. Less expensive units use a less stable, bolttogether construction or don’t come with a table at all. A less stablecutting table leads to less accurate plasma cutting and a lessefficient machine.A word of caution should be mentioned aboutany tool. Although an incredible powerful cutting machine, a plasmacutter can also do terrible damage to the human body. Besides workingsmart, an operator should wear goggles (shade #5), gloves andprotective clothing.
